Title: Autonomous traveling vehicle
Inventor: HATTORI AKIRA
IPC: G05D1/02
Filed: 1989-04-12
Abstract: PURPOSE:To attain the autonomous travel of a self-traveling vehicle through various intersections without using any special drive pattern by setting an imaginary guide line within an intersection when the intersection is decided at the front of the vehicle and traveling the vehicle along the imaginary guide line as well as a guide line set out of the intersection. CONSTITUTION:The image pickup signal of an image pickup means 1 which picks up the image of the road surface conditions including a guide line set in front of a self-traveling vehicle, the road surface structure, etc., is inputted, and an intersection deciding means 2 decides the presence of an intersection at the front of the vehicle based on the road surface structure. Under such conditions, an imaginary guide line setting means 3 set an imaginary guide line within the intersection. Thus the vehicle can autonomously travel via a drive control means 4 along the imaginary guide line as well as a guide line set out of the intersection. As a result, the self-travel of the vehicle is attained along the guide lines like the edge of the road, a white line, etc., outside the intersection based on the signal picked up by the means 1. At the same time, the vehicle can autonomously travel along the imaginary guide line set within the intersection by the means 3.

Title: Flow meter for karman's vortex street
Inventor: TSURUOKA MICHIHIKO
IPC: G01F1/32
Filed: 1981-06-15
Abstract: PURPOSE:To improve a detecting sensitivity, by a method wherein a pressure produced at both sides of a K arm an's vortex street generating substance is fed to a room having an isosceles triangular section, and a vibrating plate, having a vibrating fulcrum positioned at a top, is mounted in a room to find a discharge from the number of vibrations thereof. CONSTITUTION:A room 10, having an approximately triangular section, is  formed at a center of a housing 7, pressure introducing holes 8a and 8b are provided in wall surfaces 11a and 11b thereof, and are connected to parts in the proximity of both sides of a K arm an's vortex street generating substance through holes 9a and 9b. A vibration plate 12 is inserted into the room 10 so that it is located in a play at the periphery, and one end 13 is rockably secured with a bearing 14 acting as a fulcrum. A plate 23 is installed to the end of the room 10 located facing and opposite to the bearing 14, and light is fed through the hole in the plate 23 through optical fibers 17 and 18 to find a discharge through measurement of the number of vibration of the vibrating plate 12. This causes the vibration plate 12 to be firmly adhered to the wall surface 11a and 11b, which results in bettering interception of the transmission of vibration and improving a detecting sensitivity.

Abstract: PURPOSE:To mount an electronic component on a board at a high speed by providing optical means moving laterally to cross the moving direction of a transfer head between an electronic component supply unit and a board positioning unit, and observing the component to be transferred to the board at an intersection point. CONSTITUTION:Since a transfer head 6 moved on a predetermined component feeder 3 of an electronic component supply unit 1 to suck an electronic component P passes above a light source 12 on the way of feeding the component P to a board 5, the light of the source 12 is emitted from below to the component P at its intersection point, the silhouette of the component P is clearly observed by a camera B to detect its positional deviation. The deviations in X and Y directions are corrected by regulating X and Y direction strokes of a transfer head 6 by X-Y tables 10, 11, and the positional deviation in a thetadirection is corrected by driving a motor M and rotating a nozzle 7 around its axial center. Accordingly, time required for observing the component is eliminated, and a mounting speed can be accelerated.

Title: Protective relay device having breaker nonoperation countermeasure function
Inventor: OKADA AKIRA
IPC: H02H3/05
Filed: 1990-04-06
Abstract: PURPOSE:To prevent the erroneous output of a CBF signal in ground on the secondary side of a current transformer by making the secondary currents of the current transformer flow through one input coil and making the secondary grounded-circuit currents of the current transformer flow through the other input coil. CONSTITUTION:When a ground fault is generated at the secondary side F2 point of a current transformer CT1 on the state in which normal load currents I0 flow, only currents I2 flow through the operating coil OC of a ratio differential relay 7 because the secondary currents I1 of the current transformer CT1 flow from a ground point F2 to the E2 point   E1 point of a ground, and a circuit breaker CB1 is tripped. When the circuit breaker CB1 is tripped and potential difference is generated between the ground points E2 and E1 of the current transformer CT1, circulating currents Ik flow through the operating coil OC of a percentage differential relay 87. Even when the circulating currents Ik flow through the input coils FC1, FC2 of an overcurrent relay 51F1, however, magnetic fluxes generated by both currents mutually off set because the directions of currents are opposed mutually, thus bringing an output from an output coil FC3 to zero.
